Dear all,

I have a doubt regarding the overall procedure of a Pega upgrade. What I could not identify so far is how potential delta changes can be invoked into the overall process. Let me introduce and explain the following illustration, I will help to explain and understand where I am coming from:

• Let us assume that we have an existing P7 application hosted in the three environments DEV, TEST and PROD.
• The productive application is used by several business units and must be supported continuously.
• We want to upgrade to Pega 8 and use new servers in every environment.

The high-level process would then (more or less) look as follows:

1. The P7 Rule Base will be copied to the new P8 environment in DEV stage.
2. The upgrade to P8 will be performed in DEV stage.
3. Upgrade related issues will be identified and fixed in the upgraded P8 DEV stage.
4. The P7 Rule Base will be copied to the new P8 environment in TEST stage.
5. The upgrade to P8 will be performed in TEST stage.
6. Upgrade related defect fixes (developed in step 3) will be applied to TEST stage (import of updated rules)
7. Business unit reports an incident on the productive P7 application.
8. Incident fix for the production issue is developed. The fix consists of three P7 rules which are exported using a product rule.
9. The incident fix product rule is imported to the TEST stage (where it will be tested and approved).
10. The incident fix product rule is imported to the PROD stage.

Let us now come to my actual question:

The P7 based incident fix must be applied also to the P8 environments. Can this be done by simply importing the product rule generated at the P7 DEV stage?

Thanks and regards

Stefan
